I also fly warbirds and other large flapped airplanes. I can tell you that a delay of 22 on the elevator to account for changes in trim during flap deployment is very large and I have never needed to go that large. Aside from that, there are no conditions available in the aerobatic mode, only glider and heli so if you are flying using those menus then conditions will not be available to you.
For airplanes you can use the camber menu to control flaps.
